As for sujūd al-tilāwa (the prostration of recitation), some scholars hold that it may be performed without ablution. In any matter where the jurists have differed over its permissibility, there is unanimous agreement that the one who does it is not to be deemed an unbeliever. The majority of scholars also maintain that if a person apostasizes, his wife is not separated from him unless her waiting period finishes and he has not returned to Islam. And Allah knows best.
